The written order for the use of the atomic bomb against Japanese cities was drafted by General Groves. President Truman and Secretary of War Stimson approved the order at Potsdam. The order made no mention of targetting military objectives or sparing civilians. The cities themselves were the targets. The order was also open-ended. "Additional bombs" could be dropped "as soon as made ready by the project staff." | ||
